United States Patent() HINGE lJohn Sunko,Elgn,-lll.,assignorto'MotorolmInci, Chicago,`l1l., a corporation of IllinoisApplication September 21, y195B, SerialrNo.:3,81;I72 2 claims. (c1.22o-31) hinged at one edge and are usuallyheld Ltogether by a suitableclasp at an opposite edge. y:It is most desirable to provide such areceptacle for a radio receiveror the like that lends itself readily toa molded construction-and in which the two sections may be hingedtogether yquickly -and conveniently.

Itis, accordingly, an object of the presentinvention Vto provide animproved hinged structure comprising Ia pair of casing sections hingedItogether in an improved andl sirnpliiied manner.

Another object'of the invention'is togprovide-suehfan improved hingedstructure that-may be manufactured simply and expeditiously and withoutthe need -for heat fusing or other relatively difficult andtime-consuming operations.

Another object oftheinventionisztoprovide such an improved hingedstructure that lends .itself readilyito a molded construction.

A feature-of the present invention is-,the provision of a hingedstructure that comprises afpair of casing sections having v.slots formedin theiradjacenttedges and which are hinged together by a simplehinge-pin that may be readily inserted in the slots and which has abent-over end portion which engages a notch in one of the casingsections and holds the pin against longitudinal movement.

Another feature of the invention is the provision of such a hingedstructure in which the casing sections have slots with open sides moldedin their adjacent edges, and in which the sections are hinged togetherby a simple hinge pin retained in the slots by means of a pair ofwashers which also function as bearings for the sections.

The above and other features of the invention which are believed to benew are set forth with particularity in the appended claims. Theinvention itself, however, together with further obje-cts and advantagesthereof, may best be understood by reference to the followingdescription when taken in conjunction with the accompanying drawing inwhich:

Figure l is a perspective View of the hinged structure of the invention;

Figure 2 is an exploded view of a portion of the structure; and

Figure 3 is another view partly in section of la portion of thestructure.

The invention provides a hinged structure which comprises a firstsection having an edge with a pair of aligned slots formed therein andspaced along the edge. The rst section has an opening therein adjacentthe edge and adjacent one of the pair of slots at the end thereof remotefrom the other of the pair of slots. The structure also includes asecond section having an edge with a slot in fhinged relation 'portionextending beyond vthe one of vthe pair of `'slots "herein and extendingalong the'edge'.

A hinge .pin is providedwhich extends through the'pair of slots inthefrs't section and through -the-slotin thesecondsection formaintaining the sections The hinge pin has Ia bent-over end adjacent theopening Vreferred to above, the end rportion being disposed in theopening to prevent longitudinal movement of the pin.

fflWith referenee'now to the drawing, -the hinged struc- :ture`illustratedltherein includes Ya first-casing section 10 vand a Asecondcasing `section, Y11. VVThe .casing 4sections preferably are ofmoldedzconstruction and eachihas a "top 12 fwithfour integral .sides 513extendingrperpendicu- 'larly therefrom.

These washers functionas bearings for the structureland also :.serve Vto -retain pintZl within vthe=slots A-17 Land y18 -byengaging the -rear of notch 14.

Hinge pin 21'has `a bent-over Vend yportion 2A-which A-exten'dsbeyondthe outer=end of LVAslot 17fand=whichfis turned into notch v19 -toprevent longitudinal movement of the pin and to retain the pin inthel-slot.

The hinged structure may be assembled simply and conveniently in thefollowing manner. As previously mentioned, casing sections 10 `and 11,together with the protruding portions 15, 16 and 20, may be formed byusual molding techniques. The casing sections are laid open atapproximately with the hinge receptacle slots aligned to receive thehinge pin. Washers 22 and 23 are then dropped into position between therespective inner ends of portions 15 and 16 and the ends of portion 20.Hinge pin 21 is then inserted through slot 17, washer 23, the slot inportion 2G, and through washer 22 into slot 15. The end portion 24 ofthe hinge pin is then turned into notch 19 to prevent longitudinalmovement of the pin. In this manner, the washers retain the hinge pinagainst lateral movement within slots 17 and 18 and the end portion 24in notch 19 retains the hinge pin against longitudinal motion. As shownin Figure 1, it is preferable to provide two hinge assemblies in thehinged structure, one Vat each end.

The invention provides, therefore, an improved hinged structure in whicha pair of casing sections are held in hinged relation by a simple pinrather than a more complicated form of hinge and which does not requireheat sealing or other complicated expedients for retaining the hinge inthe sections. The hinge retaining slots in the casing sections of thepresent invention are shaped to facilitate molding of the sections. Ineach instance, the

v hingedrrelationV between the sections isv establishedrby means ofafsimple metal rod or pin which is bent over at one end and retained :inthe manner taught herein to Vprevent longitudinal motion, and a pair ofwashers is disposed on Vthe pin which functions as bearings andlretainers for the assembly.

While a particular embodiment of the invention has been shown anddescribed, modifications ymay be made and it is intended in the appendedclaims to cover all such modifications as fall within the true spiritand scope of the invention; Y
